rand function in MS Word

2012-05-01T23:03:00.002+05:30

A popular trick to surprise friends as

Open MS-Word
type =rand(200,99)
then see what happens

Have you tried the same. If not try now.....
It will print a lot of characters and will take about 200-600 pages depending upon the version of MS-Word you have

Some thinks as it is a drawback of MS-Word

For those who think the same, the answer is the one and only one, it is not a drawback of MS-Word as its a feature of MS-Word.
rand function in MS-Word prints a sample text.
Uses of Sample text:-

to test various styles
to test various formatting
to test feature like mail merge and much more...

Now lets start from basic of this function
I think we all know that Microsoft classifies MS-Word in two categories

MS Office 2003 or lower
MS Office 2007 or higher like MS Office 2010

This feature also depends accordingly on the versions...

What the sample text will be?

The sample text depends on two things
--> version
--> arguments passed through it

Version

In MS-Word 2003 or lower the text will be consist of no. of lines of a line "The quick brown fox jumps over the lazy dog" which contains all alphabets from 'a' to 'z' in a systematic manner.
In MS-Word 2007 or higher version, the text will be consist of several lines of MS Word help which gives idea about several features of MS-Word like Insert tab, themes and much more

Arguments Passed

We can use rand functions in three different modes

With two arguments
With one arguments
With no argument

The basic syntax of rand function is

=rand(x,y)

where x represents number of paragraphs,

y represents number of lines per paragraph

When we pass rand function with two arguments it will set the length of line as well as paragraph accordingly
When we will pass rand function with one argument , the number of paragraphs will be controlled and the lines per paragraph will be default (3 lines per paragraph for MS-Word 2007 version and higher and 5 lines per paragraph for MS-Word 2003 version or lower)
When we will pass rand function with no argument both the value of lines per paragraph and no. of paragraph will be taken as default (3 lines per paragraph for MS-Word 2007 version and higher and 5 lines per paragraph for MS-Word 2003 version or lower)

The maximum value of lines per paragraph can be 99
and the maximum number of paragraphs is 200

Because of this when we type =rand(200,99), MS-Word generates about 200-600 pages in less than 2-3 seconds...

'con' folder in WINDOWS

2012-04-29T13:34:00.002+05:30

Have you ever tried to create a folder at any place in windows of name 'con'?... If not, try it now.......

Can we create 'con' folder in windows? If yes then how. and if not then why?

and the ANSWER is YES as well as NO

We cannot create con folder normally but can create the folder by following a special route too.

Why we cannot create con folder in windows
--------------------------------------------------------
we cannot create any folder by naming it as 'con'. The main reason behind the same is windows follows the rules and regulations of its previous version. Earlier when windows was not there, we all were using DOS operating system. Windows also follows the rule of the same too

'con' was basically used in DOS for "console"

as it was essential for DOS, 'con' was moved to the list of reserved words which we can't use to name any file, folder

Although beside 'con' there are some other reserved words to which windows is following from DOS and cannot be used to name folders or files. Some other reserved names are:-
♦ AUX - auxillary device, usually a serial port
♦ NUL - Bit bucket device
♦ LPT1 - First Parallel printer port
♦ PRN - System list device, a parallel port
♦ COM1 - First serial communication port
♦ Drive letter (A: to Z:) and much more

Whenever we will try to use any one name from reserved word list, the name of that folder or file will automatically revert to default, g i.e. its previous one.
Moreover, when we try to name a file of a file of notepad, wordpad, paint or any other, we will generally recieve an error message windows similar to the window which is shown following

Now a question occur if it is restriction of windows then is there any way to break it? The answer is YES. As we also find out the way for the same although we are Zealous Engineers.

It can be done by entering some sequence of commands via the command prompt also known as cmd to circumvent the restrictionsof the window OS. Although it is not preferred as it maycause other problems and it is not advisable, especially for untrained and inexperienced users of windows.......

The way to crack this restriction is given below

- Start>run>cmd

- enter "md \\.\d:\con" without quotes

it will create con folder in d: partition

when you will be able to create con folder you might be confused to use this folder i.e. copy anything to this or remove

to copy:-

- open cmd

- copy \\.\d:\con

it will copy contents from source address to con folder situated in d:

But in cmd you cannot change directory to con folder

to see list of files in con folder use following command
- open cmd

- dir \\.\d:\con

At last to delete folder named as con which cannot be deleted normally can be deleted as

- open cmd

- del -r \\.\d:\con

- type 'y' then enter

- rd \\.\d:\con

Now the question may arrise to your mind that how it is happening

Actually we are using the concept of UNC path.
UNC (Universal Naming Convention) describe the comman syntax to describe network resource shared file, directory, or printer. Although this method of creation of con folder will not exist in pur DOS OS. It can be used in windows with no error. The syntax for the same is

\\remotehost\sharefolder\resource

| |__________|

| |

| V

| path

Computer name/IP Address

The major question arrises here as now we are not having process on remote host then how this command make sense?

The "." in the command "\\.\d:\con" represents the local server. Now, we are pointing to our own computer as we have all the privillages on every folder to our computer.

now last question may arrise that now why con is not reserved word? the answer for the same is there is no console taken in remote host control. As a result we can create the same

At last. How is it????.....
Reply your views by leaving your comments so that we can post accordingly to your needs as too much things are still waiting to reveal..........

Atlast, We want to say, enjoy your study or work by being More practical as much as u can by breaking all the engineers boundaries although we are ZEALOUS ENGINEERS....................

Step-1 : Possible outcomes : Piece not facing to u

2012-04-03T11:57:00.002+05:30

2. Piece which we have to solve is not facing to you then apply this algo

--> firstly place the piece exactly to the opposite of the required position i.e. below req. position.

--> then move front side two times and thats all

Lets me explain with an example

Piece - orange-white but place below position of green-white.

Initial position but showing the color below orange i.e. with bottom layer which is not facing to you

Placing piece exactly below to required position

Rotating front side two times

RETURN TO STEP-1 PAGE
to proceed to next step

Step-1 : Possible outcomes - piece facing to you

2012-04-03T11:39:00.000+05:30

1. Piece which we have to solve is facing to you then apply following algo

F`, R`, B`, R, F2

e.g.

Piece white-red which we have to solve
firstly place that piece exactly the req. position

After first step of algo i.e. F`. Where F' means Front side anticlockwisely

After 2nd move of algo i.e. R` i.e. right side snticlockwisely

Afetr 3rd move of algo i.e. B` i.e. bottom layer anticlockwise (apply this move by
taking bottom layer firstly as front layer) then move it anticlockwise

After 4th move of algo i.e. R i.e. right side clockwise

After 5th and final move i.e. F2 i.e. Front side clockwise 2 times

Solving Rubik's Cube STEP-I

2012-03-04T10:04:00.002+05:30

Solving the Rubik's cube is not a big task as we can solve the same by going through a systematical procedural steps. For solving Rubik's Cube we have to solve the same piece by piece, just like other puzzles like jig-saws and other ones.

As there is a procedure (technically known as algorithm or in short algo) to solve this cube. This algorithm is sub-divided into a number of steps. Lets move on to step 1.

NOTE:- Throughout all this procedure after a step there must be no damage with previous steps corrected pieces.

Lets Start.............

Step 1:

Solving the edge pieces of the top layer

In this very first step, we have to create a '+' sign on your Favorite color side by solving the edges of your favorite color layer i.e. just four pieces

Here I am taking my Favorite color as white

Again coming to its basics that center pieces cannot be moved which means that to solve the edge we have to take edge pieces to their correct positions

Now take side which have your favorite color at center as an upper layer.

For this there is no hard and fast rule as it can be solved with ease.

But REMEMBER one thing that bring white edge pieces to the white center and not the white center to the edge pieces

Lets explain its possible outcomes which may occur in this level

The main basic rule to make it is to take the piece which we have to solve to the correct place.

Now take your piece exactly under its correct position. by rotating lower layer i.e. last layer.
and take the side in which you have a piece to solve by placing upper layer as upper one as a front side.

Now there will be two possible outcomes

1. Piece which we have to solve is facing to you

2. Piece which we have to solve is not facing to you

There should not be case of figure (a) and
trY to solve to figure (b).

Rules of rotation to solve Rubik's Cube

2012-03-04T09:41:00.001+05:30

Throughout this session we will use some rotating notations which helps to convey the process of solving the same through writing the procedure. We have given a letter to every side

F (means front of rubik's cube, the face of cube facing to solver)
B (means back of rubik's cube, the face exactly opposite to front face)
R (means right face of rubik's cube)
L (means left face of the rubik's cube)
U (means upper face of rubik's cube)
B (means bottom face i.e. exactly opposite face to upper face of rubik's cube)

If we will write only the letter say R then it means rotate that side clock-wisely as here move right side clock-wisely.

If there is a letter with apostrophe sign i.e. (') sign without brackets, it means move that particular side anti-clock-wisely

If there is a number (say n) written after a letter it means move that particular side n times

clock-wisely.

How to solve Rubik's Cube in about 3-4 minutes

2012-02-12T21:47:00.000+05:30

Solving a rubik's cube is never a big task. It can be solved by just giving full concentration and observing some patterns. Its not just like that you have to learn too much algorithms which you may find on some other sites by googling. Its just the matter of interest with full concentration and ability of observation. Nothing more than that.

For solving Rubik's Cube. There are some conditions which we have to kept in our mind throughout this tutorial....
☻We cannot move the center piece of rubik's cube.
☻All pieces have only and only one correct position. We just have to bring the same on that position.
☻Never go for completing all colors on a side. Just work on bringing the piece at its correct position.

Future Technology: Visible Light Communications

2011-10-21T11:19:00.000+05:30

A-solid state lightening based on high-output LEDs becoming more popular in this technological world. It is proverbial light bulb above the heads of some future looking engineers as it can turn the communication medium to visible light one.

The main question which arises in every engineer is that----
"Why we are not using LEDs for communication with its two states on and off as fast as billionth part of second which we can't from our human eye, and why we are not using the same for data transferring too as it have very less chances of loss of data as It have capability of transmitting signals?"

For advancement, every new LED could also be connected to network and for the same we require a network with expand ability feature for accomplishment of ubiquitous wireless communication to a device without burdening crowd already present in the network crowded by various radio-frequency bands.Visible light communications (VLC) is being refined by various industries, standards groups too to create products based on the same, since the traditional lighting market is measured in trillions of dollars and the transition to solid-state has already begun.

Visible Light Communication is totally based on Visible light and uses light emitting diodes (LEDs), for the dual role of communication and data transmissions at a faster rate with minimum losses. It is more appreciated by industries as this spectrum is free to use and have less crowd as compare to other frequencies like RF, Infra-red and some other. It will overcome various drawback too due to more efficiency With this leading edge technology, data including video and audio, internet traffic, etc, can be transmitted at high speeds using LED light.

Just as brake lights "tell" drivers to stop, VLC could send the same message

to engine-control units for collision avoidance.
VLC technology has the potential to deliver data transfer capability at hundreds of megabytes per second. Light radiation neither constitutes nor suffers from EMI making VLC a very attractive technology in places where EMI may be an issue, such as in hospitals and in air crafts etc. In addition, where security of local communication is important eg defense and fanance applications, D-Light technology offers a secure medium for communication in an office/building environment.

Dual use of LED lighting for illumination and communication would enable ubiquitous computing,

with separate data streams for each device in the room.

VLC Applications:

A wide range of applications would benefit from using novel visible light communications:

WiFi Spectrum Relief - Providing additional bandwidth in environments where licensed and/or unlicensed communication bands are congested
Smart Home Network – Enabling smart domestic/industrial lighting; home wireless communication including media streaming and internet access
Commercial Aviation – Enabling wireless data communications such as in-flight entertainment and personal communications
Hazardous Environments- Enabling data communications in environments where RF is potentially dangerous, such as oil & gas, petrochemicals and mining
Hospital and Healthcare – Enabling mobility and data communications in hospitals
Defence and Military Applications – Enabling high data rate wireless communications within military vehicles and aircraft
Corporate and Organisational Security – Enabling the use of wireless networks in applications where (WiFi) presents a security risk
Underwater Communications – Enabling communications between divers and/or remote operated vehicles
Location-Based Services – Enabling navigation and tracking inside buildings.
